Using linear approximations seems to work decently to calculate location using a distributed architecture. AKA using cellphones to geolocate each other rather than triangulate strictly from basestations, and using it like a graph node network so your tracking ability can reach like a tentacle into buildings and closed spaces, assuming nobody is feeding fake info...

So this is the intermediate solution to Cloudflare CAPTCHA's disturbing every connect via Tor. You get 30 tokens for one CAPTCHA, which you burn for subsequent passes through Cloudflare until you run out.

Eyewear with retroreflective tape, reflecting visible/IR light. I suppose one could say this is anti-surveillance/anti-paparazzi gear. But, while they may not get your face, you stick out like a sore thumb on IR CCTV surveillance footage at night.

Using tweaked glasses which present some fake facial features due to overlay on the thick frame, it might be possible to adversarially fool face recognition systems (potential "I am Sparticus" effect) but the researchers cheated a bit and did the overlay glasses on an existing picture, rather than live humans wearing real defensive glasses.

Supposedly a windows 10 telemetry block hosts file, but the 0.0.0.0 routing will probably get noticed by the OS. Note W10 telemetry is hard coded, so putting this file on a W10 box does nothing, it must be done by the upstream DNS.

So these guys drop a cookie on a PC browser, to get it to emit ultrasonic tones via speakers (similar tones during ads on TV). If their SDK is in your smartphone, a mic accessible app now knows to assoicate that PC/TV with that smartphone. SDK installed in 18 million smartphones...

Facebook trying to patent logging camera artifacts to connect together unattributed photos "for social network purposes". Which means they now posess deanonimization technology given a large enough body of pictures to datamine, since they can now fingerprint the camera, and by extension associate it with certain circles of people or a certain owner.

So japan's National Institute of Informatics decided making a set of eyeglasses that disrupt facial recognition algorithms would make a good crowdfunding campaign. I suppose this is marginally more acceptable than facedazzle makeup, but without the IR LED's to blind security cameras, this probably has limits.

Tries to be secure by using tor, plus a little tit-for-tat network load sharing (use uplink for the network onion routing for other peers). Though that means you might be classed as an exit node of sorts, plus naturally it's slower than clearnet due to the onion routing.

Looks like some dude using a cheap chinese mini-router and claiming to be custom hardware, and he got busted for doing so by the reddit lynchmob. Probably safer to use grugq's PORTAL and a generic TP-link router...

So, people are trying to return the anonymity of cash back into bitcoin, which by its nature is a very public currency protocol. Though it sounds like they are doing this via zerocoin based protocols, so effectively there will be value entering and exiting the bitcoin blockchain at some point, but the intermediate transactions in zerocoin/zerocash will become private. Maybe.
